I remember my first experiences with touch screen phones. It was magic, and it was clear that this would change the world. Touch screen phones were the biggest and final "dent in the universe" Jobs made.
But it was not as magic and promising as my first experiences with AI that I had over the last 24 months or so.
AI is a much bigger step for mankind than home computers and smartphones. So Altman is involved in making much bigger dents in the universe than Jobs was.
